Tel Aviv University Dear all, Next week the Horowitz seminar will hold its final meeting for the semester. We are happy to have: Speaker: Piotr Milos, University of Bath and University of Warsaw Title: Heavy-tailed branching Lévy motion in inhomogeneous potential Date: Monday, January 21 Time: 14:30 Place: Schreiber 309 Abstract: In my talk I will present results concerning a branching system as follows. Particles evolve according to a real-valued Lévy motion with heavy tails and branch according to a dyadic branching law. We consider three different regimes of the branching rate: - constant in space, then the system size grows exponentially. - \beta \log(x), then the system size grows as exp(exp(\beta/(e \alpha)t)). - \log^{1+\epsilon}(x), then almost surely the system explodes, i.e. produces an infinite number of particles in finite time. These are joint results with Simon Harris (University of Bath) Have a good semester end!
